Macrovision’s InstallShield Wins Fifth Consecutive Visual Studio Magazine 2005 Readers Choice Award

Developer Community Votes InstallShield as Best Installation, Setup and Deployment Tool

SANTA CLARA, CA - May 31, 2005 - Macrovision Corporation (NASDAQ: MVSN), the leader in Software Value Management, today announced that readers of Visual Studio Magazine have voted InstallShield® as the industry’s strongest and most effective solution for installation, setup and deployment for the fifth year in a row.

"The Reader’s Choice Awards from Visual Studio Magazine are significant because the developers who use these products have the sole vote in the judging process," said Patrick Meader, Visual Studio Magazine editor in chief. "To win a Reader’s Choice Award is to have made your mark in the only place that matters: the heart of a developer who wants to get work done faster and more easily. It is a special mark of distinction to win over multiple consecutive years, because it means you’ve really struck a chord with what developers are looking for."

InstallShield’s win underscores the product’s ease-of-use and comprehensive technology support that continues to make it the de facto installation standard across platforms, operating systems or devices. Fully integrated into the Visual Studio® .NET™ design environment, InstallShield saves software developers valuable development time while greatly increasing deployment successes with lower support costs and higher customer satisfaction. Earlier this month, Macrovision introduced InstallShield 11 and InstallShield Activation Service, which offered an industry-first solution, enabling software publishers to include piracy protection for their products at the same time they wrap them for installation,
"This recognition by Visual Studio Magazine readers is a testament to InstallShield’s continued leadership as the setup tool of choice for Windows-based systems and all operating platforms," said Bob Corrigan, product manager, installation tools, Macrovision. "We’re delighted to have won this vote of confidence yet again and, with our recent introduction of Activation Service in our latest release of InstallShield 11, we continue our commitment to providing software publishers with solutions that allow them to maximize the value of their software."

InstallShield and InstallShield Activation Service are core components of Macrovision’s FlexNet™ line of Software Value Management solutions, which include software installation, updating, packaging, licensing, entitlement management, end user management, and usage optimization.
